Ctenophora, commonly known as comb jellies or sea gooseberries, is a phylum of marine animals found in oceans around the world. They are unique and often strikingly beautiful creatures, known for their bioluminescence and iridescent, comb-like rows of cilia that they use for locomotion. Despite their name, comb jellies are not related to jellyfish; they belong to a separate phylum.

Transparent Bodies: Most comb jellies are transparent or translucent, allowing observers to see their internal structures, including their digestive system and bioluminescent cells.

No Stinging Cells: Unlike jellyfish, comb jellies do not possess nematocysts. Instead, they rely on adhesive cells to capture prey.

Carnivorous Lifestyle: Comb jellies are carnivorous and primarily feed on other small marine organisms, including zooplankton and other small invertebrates.
